Embodiment 1

[0081]Weigh 5% etesulfuron-methyl, 5% penoxsulam, 30% cyhalofop-ethyl, 4% TERSPERSE 2700, 3% diffusing agent NNO, 1% pull open powder BX, 1% K-12, 10% soluble Starch, 10% glucose and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 40% ethersulfuron-pentoxsulam-cyhalofop-methyl water-dispersible granules.

Embodiment 2

[0083] Weigh 5% etesulfuron-methyl, 10% penoxsulam, 60% cyhalofop-ethyl, 3% TERSPERSE 2700, 4% sodium lignosulfonate, 1% pull-off powder BX, 1% K-12, 1 % carboxymethyl cellulose, 3% urea, and diatomaceous earth are added to 100% by weight. The above raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 75% ethersulfuron-pentoxsulam-cyhalofop-methyl water-dispersible granules.

Embodiment 3

[0085] Weigh 10% etesulfuron-methyl, 5% penoxsulam, 25% cyhalofop-ethyl, 4% TERSPERSE 2700, 1% pull open powder BX, 2% K-12, 0.5% dextrin, 10% ammonium sulfate , Attapulgite added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 40% ethersulfuron-pentoxsulam-cyhalofop-methyl water-dispersible granules.

Abstract

The invention discloses a herbicide for preventing and killing off grassy weeds, broadleaf weeds and sedge weeds of paddy fields, which is a ternary herbicide composition mixture consisting of cinosulfuron, penoxsulam and cyhalofop-butyl serving as active ingredients. The weight ratio of the cinosulfuron to the penoxsulam to the cyhalofop-butyl in the composition is (1-16):(1-16):(4-64), and preferably (1-2):(1-2):(5-12). The complex herbicide can be prepared into water dispersible granules, wettable powder, a suspending agent and a dispersible oil suspending agent. The composition is used for preventing and killing off the weeds of the paddy fields, so the components are reasonable, the weed preventing and killing spectrum is expanded, the grassy weeds, the sedge weeds and the broadleaf weeds are prevented and killed off by applying the herbicide at one time, the frequency of applying the herbicide is reduced, the preventing and killing cost is lowered, the production of weed resistance is slowed down, the safety of crops is high, and the requirements of pesticide preparations on the safety are met.

Description

technical field [0001] The present invention relates to a herbicide composition containing etesulfuron-methyl, in particular to a herbicide for controlling gramineous weeds, broad-leaved weeds and Cyperaceae weeds in paddy fields, which consists of etesulfuron-methyl, A ternary herbicide composition in which penoxsulam and cyhalofop-ethyl are active components. Background technique [0002] With the continuous use of many herbicide varieties in large areas of rice fields, many problems have arisen, which can be summarized as follows: ①Weed resistance is outstanding, among which barnyardgrass is resistant to propanil, quinclorac, butachlor, and dicarbap The resistance is relatively prominent. Recently, common weeds such as Cyperaceae, Rhizomaceae, Alismaceae and other common weeds such as heteromorphous sedges, fireflies, Arthia sativa, Yujiuhua, and Coriaceae have developed resistance to sulfonylurea herbicides. resistance, complicating the problem of weed control. ② Peren...
